Income Tax Tool

From 6 April 2019, income tax rates paid on non-savings, non-dividend (‘NSND’) income by Welsh taxpayers will fall by 10p in the pound and will be replaced by the Welsh Rates of Income Tax.

Keeping tax rates paid by Welsh taxpayers unchanged by setting a 10p rate in each band is forecasted to raise over £2 billion for the Welsh Government in 2019-20.

This model has been produced in partnership with researchers from the Welsh Governance Centre at Cardiff University, using modelling from the Wales Centre for Public Policy’s report: The Welsh Tax Base, July 2018.

Adjust the sliders to vary the income tax rates and behavioural changes and see the effects on the Welsh Government's income tax revenue. Enter your annual taxable income to see how much you pay the Welsh and UK Governments and where you lie in the Welsh income distribution.

*Were the Welsh Government to change income tax rates in Wales, there would likely be some behavioural response from Welsh taxpayers. Possible behavioural responses include greater use of tax planning, tax avoidance
or evasion, individuals seeking different jobs or changing the number of hours worked, and/or migration into and out of Wales. The extent and effects of behavioural change to be expected is highly uncertain, though
it must be considered when setting income tax policy.
